This standard specifies a general method for the determination of mercury in inorganic chemical products by flameless atomic absorption spectroscopy (AAS), applicable to the determination of mercury ion mass concentrations between 0.04 µg/mL and 40 µg/mL. Absorbance measurement of mercury at 253.7 nm using AtomicAbsorption Spectroscopy is performed by dissolving the sample in an acidic solution and reducing the mercury compound to elemental mercury vapor using a reducing agent. The accuracy and suitability of this method can be adjusted according to the criteria for the product being analyzed.
